[0021] 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.

[0022] See also Figure 1-5 The utility model provides an embodiment: a special device for removing cylinder barrels from four-way matching of a vehicle engine.

[0023] It includes: a support frame 01, a screw rod 02 passes through the middle of the support frame 01, a connecting pin 03 is connected to the bottom of the screw rod 02, a weight 04 is arranged on the inner side below the connecting pin 03, the connecting pin 03 and the weight 04 are connected by a bolt 05, the bolt 05 is passed through the hole of the weight 04, and is screwed into the connecting pin 03, so as to fix the position of the weight 04, a guide piece 06 is arranged in the middle of the support frame 01, the guide piece 06 plays a guiding role for the screw rod 02, a sleeve 07 is arranged on the upper periphery of the screw rod 02, the sleeve 07 plays a supporting role, when the nut 08 is screwed, the position of the nut 08 remains unchanged, the screw rod 02 can move upward, the upper outer wall of the screw rod 02 is connected with the nut 08, when the nut 08 is screwed, the screw rod 02 moves upward, and can drive the weight 04 and the cylinder barrel to move upward.

[0024] Furthermore, the support frame 01 is provided with holes corresponding to the screw rod 02 to ensure that the support frame 01 does not affect the movement of the screw rod 02. The screw rod 02 moves upward, which can drive the weight 04 and the cylinder barrel to move upward.

[0025] Furthermore, the screw rod 02 is slidably connected to the support frame 01. When the nut 08 is turned, the screw rod 02 moves upward, which can drive the weight 04 and the cylinder barrel to move upward.

[0026] Furthermore, a groove is provided on the screw rod 02 corresponding to the guide piece 06 , and the guide piece 06 guides the screw rod 02 .

[0027] Furthermore, the connecting pin 03 is fixedly connected to the screw rod 02, and a hole is opened in the weight 04 corresponding to the bolt 05. The bolt 05 is passed through the hole of the weight 04 and screwed into the connecting pin 03, so that the position of the weight 04 can be fixed.

[0028] Furthermore, the bolt 05 is threadedly connected to the connecting pin 03. The bolt 05 is passed through the hole of the weight 04 and screwed into the connecting pin 03, so that the position of the weight 04 can be fixed. The guide piece 06 is fixedly connected to the support frame 01 to ensure the stability of the guide piece 06. The guide piece 06 guides the screw rod 02 to avoid insufficient friction, so that the screw rod 02 follows the rotation of the nut 08, thereby affecting the movement of the screw rod 02.

[0029] Furthermore, the sleeve 07 is movably connected to the screw rod 02, and the sleeve 07 plays a supporting role. When the nut 08 is screwed, the position of the nut 08 remains unchanged, and the screw rod 02 can move upward. The weight 04 is larger than the cylinder barrel, which makes it convenient to place the weight 04 into the cylinder barrel, and when the weight 04 moves upward, it can drive the cylinder barrel to move.

[0030] Working principle: When using, first remove the nut 08 and the support frame 01, assemble the weight 04 with the bolt 05 and the connecting pin 03, put the weight 04 into the cylinder body, wait for the two ends of the weight 04 to be stuck on the cylinder barrel, put the support frame 01 on the cylinder body, insert the screw 02 into the hole in the middle of the support frame 01, and put the sleeve 07 on the screw 02 above the support frame 01, so that a part of the head of the screw 02 is exposed, screw the nut 08 onto the screw 02, and then use the adjustable spanner to turn the nut 08 clockwise, so that the screw 02 pulls the weight 04 upwards, and the cylinder barrel is taken out little by little. The above is the entire working principle of the utility model.
