DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 In this embodiment, a mobile phone back cover leather splicing jig includes a fixed base 1, a "U"-shaped groove is opened at the upper end of the fixed base 1, and a non-slip pad is fixedly connected to the lower end of the fixed base 1. The setting of the non-slip pad can prevent the fixed base 1 from sliding;

[0024] A fixing base 2 is fixedly connected to the inner side of the fixing base 1, and the fixing base 2 is located in the middle position of the fixing base 1. A connecting groove 201 is provided at the upper end of the fixing base 2, and a perforation is provided on the side wall of the connecting groove 201. A locking column 202 is movably connected to the inner side of the perforation. The locking column 202 is in a "T" shape, and a connecting spring 203 is fixedly connected between the locking column 202 and the fixing base 2. A supporting plate 3 is installed at the upper end of the fixing base 2, and the specifications of the supporting plate 3 are adapted to the specifications of the back cover of the mobile phone. An insertion seat 301 is fixedly connected to the lower end of the supporting plate 3, and the insertion seat 301 is located on the inner side of the connecting groove 201. A locking hole 302 is provided on the side wall of the insertion seat 301, and the specifications of the locking hole 302 are adapted to the specifications of the locking column 202.

[0025] When the lower end of the insertion seat 301 is in contact with the bottom wall of the connecting groove 201 , the position of the locking hole 302 is aligned with the position of the locking column 202 . The arrangement of the locking hole 302 and the locking column 202 allows the support plate 3 to be easily disassembled.

[0026] The upper end of the fixed base 1 is fixedly connected with a mounting frame 4, which is in an "L" shape, and a through hole is provided on the surface of the mounting frame 4. The upper end of the mounting frame 4 is fixedly connected with an electric push rod 5, and the output shaft of the electric push rod 5 is located on the inner side of the through hole. The output end of the electric push rod 5 is fixedly connected with a mounting plate 6, and the lower end of the mounting plate 6 is movably connected with a threaded sleeve 601, which is located in the middle position of the mounting plate 6, and the threaded sleeve 601 is movably connected with the mounting plate 6 through a bearing;

[0027] It should be noted that the electric push rod 5 is a device for linear motion, usually composed of components such as an electric motor, a lead screw, a guide rail and a housing. It can convert rotational motion into linear propulsion. The working principle of the electric push rod 5 is to drive the lead screw to rotate through an electric motor. The thread on the lead screw cooperates with the nut. When the lead screw rotates, the nut will move linearly along the lead screw, thereby pushing the external device to perform linear motion. This device can provide precise linear motion control and can be automatically controlled and programmed as needed.

[0028] A placement seat 7 is installed at the lower end of the mounting plate 6. The specifications of the placement seat 7 are larger than those of the support plate 3. A cavity is opened on the inner side of the placement seat 7. The side wall of the cavity is connected with a joint 701. A threaded column 702 is fixedly connected to the upper end of the placement seat 7. The threaded column 702 is threadedly connected to the threaded sleeve 601. The cooperation between the threaded column 702 and the threaded sleeve 601 makes it possible to conveniently disassemble and assemble the placement seat 7. An air pump 8 connected to the placement seat 7 is fixedly connected to the upper end of the mounting plate 6. The suction end of the air pump 8 is connected with an suction pipe 801. The other end of the suction pipe 801 is connected with the joint 701. A placement groove 9 is opened at the lower end of the placement seat 7. The specifications of the placement groove 9 are adapted to the specifications of the leather. An suction hole 901 connected to the cavity is opened on the top wall of the placement groove 9. The number of the suction holes 901 is several, and the distribution of the suction holes 901 is related to the shape of the leather.

[0029] In this embodiment, through the cooperation between the support plate 3 and the placement groove 9, the setting of the suction pipe 801 and the cavity, the suction hole 901 absorbs the leather, and with the cooperation of the electric push rod 5, the leather and the back cover of the mobile phone can be accurately spliced.

[0030] The working principle of the above embodiment is:

[0031] By providing a support plate 3, the back cover of the mobile phone can be fitted on the outside of the support plate 3. By providing a locking column 202, the locking column 202 is pulled to separate the locking column 202 from the locking hole 302, so that the support plate 3 can be replaced according to the back cover of the mobile phone of different specifications. By providing a placement seat 7 and a placement groove 9, and the specification of the placement groove 9 is adapted to the specification of the leather, the cut leather can be placed in the placement groove 9, and the air pump 8 is started. With the cooperation of the suction pipe 801 and the cavity, the suction hole 901 absorbs the leather, and with the cooperation of the electric push rod 5, the leather and the back cover of the mobile phone can be precisely spliced.
