Reference is made to the accompanying drawings. The invention provides a manual cap pulling device, which comprises a first ratchet wrench 100, a second wrench 200, a first hollow shaft 1, a second hollow shaft 2 and a cap pulling screw 3 which are arranged on the same central axis, wherein the second wrench 200 is arranged above the first ratchet wrench 100.
The first hollow shaft 1 passes through the first ratchet wrench 100, and the torque output part 101 of the first ratchet wrench is fixedly connected with the first hollow shaft 1, and the torque output part and the first hollow shaft cannot rotate relatively.
The first hollow shaft 1 has a connection 12 in the middle thereof to a first ratchet wrench, a mounting 11 in the lower part, an external thread 13 in the upper part and an internal thread.
The connecting part 12 may be a common hexagon, a D-shape or the like, the torque output part 101 of the first ratchet wrench has a central hole, the first hollow shaft 1 passes through the central hole of the torque output part 101, and the connecting part 12 forms a rotation-stopping fit with the central hole wall.
The mounting 11 is located in the housing 4 and is rotatably connected to the housing 4 in an axially positionable manner by means of a connecting element, such as a collar 40, in which housing a bearing 5 is arranged, the bearing 5 supporting the first hollow shaft 11 such that the mounting is supported by the housing; the lower part of the shell is also in threaded connection with a screw tube 6, the screw tube supports the bearing 5 at the lower part, and the screw tube 6 is in the same center with the first hollow shaft 1. The screw tube 6 can be connected with the fastening screw cap 7 in a threaded manner, so that the whole manual cap pulling device is convenient to assemble, the whole structure is reliably connected from the lower part without looseness, and larger cap pulling operation torque force can be conveniently input. The coil 6 also has a portion 60 for manual operation.
The second hollow shaft 2 is a liftable component, the second hollow shaft 2 is inserted into a hole of the first hollow shaft 1, and the insertion part of the second hollow shaft is provided with an external thread 21 which is in threaded connection with an internal thread of the first hollow shaft 1.
The second wrench 200 is a liftable component, the second wrench 200 is provided with a wrench body shell 201, a central gear 22 is arranged at the upper end of the second hollow shaft 2, the central gear 22 is clamped in the wrench body shell 201, so that the whole structure is reliably connected without looseness at the upper part, the wrench body shell 201 is provided with an inner gear ring 202, the inner gear ring 202 is connected with the central gear 22 through a transmission gear 203, the shell 201 is provided with a hole 204 corresponding to the central hole of the second hollow shaft 2, the central hole 20 of the second central shaft and the hole 204 are used for a cap pulling screw 3 to penetrate, the cap pulling screw 3 is provided with a head 30 matched with the wrench body shell 201, the middle part of the cap pulling screw is connected with a limiting clamp ring 31, and the limiting clamp ring 31 can be matched with a step in the central hole 20 of the second central shaft to play a limiting role, so that the cap pulling screw 3 is assembled in a cap pulling device.
