Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of four-color machine accessories, in particular to a folding spanner. Background Art
[0002] Four-color printing press refers to a printing press that uses black, medium blue, brown and green inks to achieve the lithographic printing method of map reproduction. It is a printing method commonly used for large-scale topographic maps in China and has a unified color code.
[0003] In a four-color machine, the switch is relatively close to the operating table. When starting the machine, the wrench needs to be turned to open it, and then removed. After removing it, the operator usually uses it on the operating table immediately and puts the wrench aside, which is easy to cause forgetting and discarding, resulting in the need to search again when using it next time. When turning it, some operators do not know the angle of rotation and sometimes turn it too far, causing certain damage to the switch. Utility Model Content
[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.
[0005] The utility model aims to provide a folding wrench, and aims to solve the problem that after being taken down, the operator generally puts the wrench aside immediately for use on the operating table, which is easy to cause forgetting and discarding. The utility model is proposed.

[0008] As a preferred solution of the folding wrench of the utility model, wherein: the slide plate is provided with hinge seats on both sides of the rotating rod, and a rotating shaft is connected between the hinge seat and the rotating rod.
[0009] As a preferred solution of the folding wrench of the utility model, the width and length of the rotating rod are both smaller than the width and length of the interior of the placement groove.
[0010] As a preferred solution of the folding wrench of the utility model, a connecting rod is connected between the handle and the switch head, and a magnet is built into the switch head.
[0011] As a preferred solution of the folding wrench of the utility model, the rotating rod is in an I-shape, and a silicone anti-slip sleeve is embedded on the outer side of the rotating rod.
[0012] The beneficial effects of the folding wrench of the utility model are:
[0013] 1. When in use, the slide plate can be rotated by rotating the rod, and then the slide plate can be pushed through the limit rod to move in the slide slot and moved into the placement slot.

DETAILED DESCRIPTION
[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0023] In this embodiment, refer to Figure 1 to Figure 3 This embodiment provides a folding wrench, including a handle 100, a switch head 300 is provided at one end of the handle 100, a placement groove 101 is opened in the middle of the handle 100, a slide plate 400 is built in the placement groove 101, and slide grooves 102 are opened on both sides of the placement groove 101. Limit rods 401 are arranged on both sides of the slide plate 400 corresponding to the positions of the slide grooves 102, and a rotating rod 500 is hinged on the end of the slide plate 400 away from the switch head 300.
[0024] During use, when in use, the sliding plate 400 can be rotated by rotating the rod 500, and then the sliding plate 400 can be pushed to move in the slide groove 102 through the limiting rod 401 and moved into the placement groove 101. When not in use, it can be folded and retracted and placed at the switch, which will not hinder the use of the operating table personnel and prevent it from being easily discarded when it is taken down.
[0025] Preferably, a rotation groove 200 is provided at one end of the handle 100 at the reverse side of the switch head 300 , a rotation circle 201 is rotatably connected in the rotation groove 200 , a horizontal level bubble 202 is built in the rotation circle 201 , and an angle disc 203 is provided outside the rotation groove 200 .
[0026] When in use, according to the rotation angle of the switch, rotate the rotating circle 201 to make the rotating circle 201 rotate to the corresponding position of the angle dial 203, and then rotate the handle 100 to switch. When the horizontal bubble 202 inside the rotating circle 201 is in the middle position, the rotation angle of the switch is reached, making it easy for people to see the rotation angle, preventing the switch from being out of place and rotating excessively, causing damage.
[0027] Preferably, the slide plate 400 is provided with hinge seats 402 corresponding to the two sides of the rotating rod 500 , and a rotating shaft 403 is connected between the hinge seat 402 and the rotating rod 500 .
[0028] When in use, the rotating rod 500 rotates around the hinge seat 402 via the rotating shaft 403 .
[0029] Preferably, the width and length of the rotating rod 500 are smaller than the width and length of the interior of the placement slot 101 , so that the rotating rod 500 can be placed in the placement slot 101 .
[0030] Preferably, a connecting rod is connected between the handle 100 and the switch head 300, and the switch head 300 has a built-in magnet.
[0031] When in use, the switch head 300 is conveniently adsorbed on the switch.
[0032] Preferably, the rotating rod 500 is in an I-shape, and a silicone anti-slip sleeve is embedded on the outer side of the rotating rod 500.
[0033] When in use, it is in an I-shape, which can reduce its own weight and make it easier to hold. The silicone anti-slip cover can prevent it from slipping during use.
[0034] Usage process: When in use, the switch head 300 is inserted into the switch, and the rotating circle 201 is rotated according to the rotation angle of the switch, so that the rotating circle 201 is rotated to the corresponding position of the angle engraved disk 203, and the rotating rod 500 rotates around the hinge seat 402 through the rotating shaft 403. When the rotating rod 500 and the slide plate 400 are 90 degrees, the rotation is stopped, and the slide plate 400 is pulled by the rotating rod 500, so that the slide plate 400 moves in the slide groove 102 through the limit rod 401. When it is pulled to the appropriate position, stop pulling the rotating rod 500, and rotate the rotating rod 500. The rotation of the rotating rod 500 passes through the slide plate. The connection of 400 drives the handle 100 to rotate, thereby driving the switch head 300 to rotate. When the horizontal level bubble 202 inside the rotating circle 201 is in the middle position, the rotation angle of the switch is reached, making it easy for people to see the rotation angle, preventing the switch from being out of place and rotating excessively, causing damage. When no longer in use, the rotating rod 500 is rotated to the slide plate 400, and then the slide plate 400 is pushed through the movement of the limit rod 401 in the slide groove 102 to move into the placement groove 101. When not in use, it can be folded and retracted and placed at the switch, which will not hinder the use of the operating table personnel.
