DETAILED DESCRIPTION
[0017] Reference Figures 1 to 3 The utility model is further described in detail.
[0018] An adjustable push rod guide sleeve comprises an upper shell 1, a lower shell 2, a locking member 3, a first limiting member 6 and a second limiting member 7. The upper shell 1 and the lower shell 2 are movably connected by a locking member 3. The first limiting member 6 is fixed on the upper shell 1, and the second limiting member 7 is fixed on the lower shell 2.
[0019] The locking member 3 includes a first positioning block 31, a second positioning block 32, a connecting rod 33 and an annular convex ring 34. The first positioning block 31 is provided with two and is respectively fixed at both ends of the upper shell 1. The second positioning block 32 is provided with two and is respectively fixed at both ends of the lower shell 2. The first positioning block 31 corresponds to the second positioning block 32. The connecting rod 33 is respectively fixed on the two first positioning blocks 31. A plurality of annular convex rings 34 arranged in sequence are fixed on the connecting rod 33 and the annular convex rings 34 are made of rubber material. A connecting hole 4 is opened on the second positioning block 32. The connecting rod 33 passes through the connecting hole 4 and an annular groove 5 is opened in the connecting hole 4. The annular groove 5 matches the annular convex ring 34.
[0020] By pulling the upper shell 1, the upper shell 1 drives the first positioning block 31 to move, and then the first positioning block 31 drives the connecting rod 33 to move, and then the several annular protrusions 34 on the connecting rod 33 move, until the lowest end annular protrusion 34 is engaged with the annular groove 5 in the second positioning block 32, and then the distance between the upper shell 1 and the lower shell 2 is pulled to the longest, and then the push rod is passed between the upper shell 1 and the lower shell 2, and then the upper shell 1 is moved to move the upper shell 1 closer to the lower shell 2, and then the upper shell 1 and the lower shell 2 respectively contact with the push rod and fix the push rod, and then the width of the guide sleeve is adjusted by moving the upper shell 1 and the lower shell 2, and then the guide sleeve is adjusted to a suitable size according to the size of the push rod, thereby improving the production efficiency.
[0021] The first limiter 6 and the second limiter 7 have the same structure. The first limiter 6 includes a spring 61, a telescopic rod 62, an arc plate 63 and an anti-skid pad 64. The two ends of the telescopic rod 62 are respectively fixedly connected to the arc plate 63 and the upper shell 1. The anti-skid pad 64 is fixed on the arc plate 63. The spring 61 is sleeved on the telescopic rod 62 and the two ends of the spring 61 are respectively in conflict with the upper shell 1 and the arc plate 63.
[0022] By placing the push rod on the second limit member 7, when the upper shell 1 moves, the telescopic rod 62 is driven to move, and then the telescopic rod 62 drives the arc plate 63 to move, and the arc plate 63 drives the anti-skid pad 64 to move until the anti-skid pad 64 contacts the push rod, and then the elasticity of the spring 61 makes the anti-skid pad 64 on the arc plate 63 squeeze the push rod, and then cooperate with the second limit member 7 to fix the push rod between the first limit member 6 and the second limit member 7. The anti-skid pad 64 can further enhance the fixing effect of the push rod.
[0023] Working principle: First, pull the upper shell 1 and the lower shell 2 respectively, so that the upper shell 1 drives the first positioning block 31 to move, and then the first positioning block 31 drives the connecting rod 33 to move, and then the connecting rod 33 drives several annular convex rings 34 on the connecting rod 33 to move, until the annular convex ring 34 at the bottom of the connecting rod 33 is engaged with the annular groove 5 in the connecting hole 4, then stop pulling the upper shell 1 and the lower shell 2, and then pass the push rod between the upper shell 1 and the lower shell 2, and then pull the upper shell 1 downward, so as to move the connecting rod 33. Move downward, and at the same time, several annular convex rings 34 pass through the connecting hole 4 in sequence. At the same time, the upper shell 1 drives the telescopic rod 62 to move, the telescopic rod 62 drives the arc plate 63 to move, and the arc plate 63 drives the anti-skid pad 64 to approach the push rod until the anti-skid pad 64 is squeezed with the surface of the push rod, and at the same time, the corresponding annular convex ring 34 is engaged with the annular groove 5, thereby fixing the push rod between the upper shell 1 and the lower shell 2. At the same time, the annular convex ring 34 is made of rubber, and the friction force of the rubber prevents the annular convex ring 34 from slipping out of the annular groove 5.
[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
