Creation instructions (2) Move toward the direction, and the strip can be sent out or retracted into the inner cylinder. Announcement No. 2 0 4 5 7 6 discloses a push-type strip pushing device. The outer tube is inserted into the outer tube axially and movably. The inner tube is contained in the strip and is connected to the tip of the outer tube. A spring provided in the outer tube to constantly push the inner tube backwards, composed of a sleeve at the front end of the inner tube and a pressing head provided at the rear end of the inner tube, which is characterized in that the inner tube sequentially forms a supply from the front end. The duct part through which the strip passes is formed with at least two pieces of lost claws which are opened rearwardly on the duct, and connected to the rear side of the clamping claw part. The three main parts are integrally formed to accommodate the content of the strip. In addition, the two cases of Announcement Nos. 10 4 9 8 8 and 10 7 0 4 6 disclose that two types of push-out strips with similar structures are sent out of the container, both of which are outer tubes, and the inner tube has a collet at the front end. It consists of a tightening ring embedded in the chuck and a spring that often pushes the inner tube backward. Both of the above two types of push-type strip containers push the front end of the inner tube away from the tightening ring by pressing the rear end of the inner tube or the pressing cap sleeved on the end, and move the strip without strip to the front of the inner tube. Send for use. According to the container No. 2 0 0 6 of the announcement, although the final structure is simple, the expansion and contraction of the strip is achieved by gravity, and the amount of each extension is difficult to control. It often needs to be adjusted by human hands. It is very inconvenient to hold down the button to prevent the bar from shrinking. Announcement No. 1 1 8 6 2 requires a spiral groove in the outer tube, which results in low production and assembly efficiency, and requires two-handed operation during use, which is troublesome. The container No. 2 0 3 8 3 8 has a screw shaft driven by an outer cylinder, which has a complicated structure and low production efficiency, and requires two-handed operation during use. The container of Announcement No. 2 0 4 5 7 6 has a structure similar to that of a mechanical pencil. The bar can be sent out at a fixed length by pressing on the back end. Only one with a non-opening M275963 is used. Note (3) The special inner tube of the drop-out chuck requires high manufacturing technology. The princess and the container of No. 10704 6 are also press-type containers. The structure of the control part between the two tightening rings is slightly different. The difference is that the front end of the tightening ring and the clamping head are exposed. At the same time, the front end of the strip is easily exposed to the outside. [New content] In view of the various strips or eraser problems mentioned above, the creator has completed the design of the new compression retractor after careful design and improvement. In particular, the purpose of this creation is to provide a pressing device, which is composed of an outer tube at both ends with an open outer tube, a slidable inner tube, and an inner tube with a clamping piece at the front end, which is set inside the front end of the inner tube It consists of a pressing cover at the rear end of the tube, and a return spring that pushes the tube backwards between the outer tube and the inner tube; Fortunately, the upper and lower parts are held in the outer tube by the short cylinders facing the slot, and the positioning protrusions are snapped into the positioning holes of the outer sleeve of the outer tube, and a pair of locking protrusions are provided on the side of the inner tube. It can be axially slidably inserted into the axial slot of the sleeve at the end for relative axial movement. When in operation, the sleeve does not substantially leave the outer tube in place.

Creation instructions (5) The locking protrusion 2 2 can be axially moved freely and snaps into this slot 34, so that the inner tube 2 and the bundle sleeve 3 are combined into one body. ^ The pressing head 4 is a cap with a pen holder 41, which can be detachably covered at the rear end of the inner tube 1 for pressing operation and closing the opening at the rear end of the inner tube 1. The pen holder 41 is convenient for inserting into the pocket, and it is not necessary if the pen holder 41 is not provided. Between the outer tube 1 and the inner tube 2 are located inside the long grooves 1 4 and 2 5 a zigzag-type return spring 5 which often pushes the inner tube 2 to the rear. In this example, two springs 5 are used on both sides of the rectangular inner tube 2, but it is also possible to use a rectangular coil spring to cover the outer periphery of the inner tube 2. Furthermore, if the inner and outer pipes are of cylindrical or polygonal cylindrical shape, a circular coil spring is appropriate. The following is a description of the assembling method of the creative pen container having the above structure. First, insert the sleeve 3 from the jaw end of the inner tube 2 into the jaw portion 20 until the slot 34 is inserted into the locking projection 22 and the inner end of the east sleeve is against the shoulder 23 of the inner tube 2. , Place the spring 5 in the long grooves 25 on both sides of the inner tube 2, hold the spring 5 with the inner tube 2 by hand, and insert the end of the outer tube 1 into the outer tube 1 with the mouth end. After the positioning protrusion 3 2 of the sleeve 3 is locked into the positioning hole 1 3 of the outer tube 1 and integrated with the outer tube 1, a strip 6 such as an eraser is inserted into the inner tube 1 from the rear end, and then covered. The upper cover 4 as the pressing head is assembled. When in use, as long as the pressing head 4 is pressed, the inner tube 2 moves forward against the resistance of the spring 5, because the sleeve 3 is locked in the positioning hole 1 3 of the outer tube 1 by the positioning protrusion 3 2 and remains in place. The jaw portion 20 of the tube 1 is taken out of the sleeve 3 with the strip 6 and the binding is moved forward, and the strip 6 can be exposed from the front neck 1 1 of the outer tube 1,
