[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped gondola for carrying people or goods in multi-story buildings. Elevators are extremely frequently used in today's mid- to high-rise buildings. To avoid safety accidents, it is necessary to regularly conduct safety inspections on all aspects of the elevator. Relevant dynamometers are required in elevator inspections.

[0003] The Chinese Patent Network discloses a dynamometer for elevator inspection and detection, with the publication number CN218822906U. Although by setting a dynamometer body, a connecting plate, a base, a movable block, a movable groove, a fixed ring, a buckle mechanism, a movable ring, a sleeve plate, a limiting block and a sliding block, this dynamometer can be made portable. The annular structure wraps the user's arm or leg and is reinforced by a buckle mechanism, thus facilitating people to carry the dynamometer body, avoiding problems such as finger joint fatigue caused by long-term holding, and meeting people's usage requirements. However, since the protective shell is fixed by inserting blocks and slots, its fixing effect is not good. With the vibration of the dynamometer, the inserting blocks may fall out of the slots, thus affecting the protective effect of the protective shell on the hook.

[0004] Therefore, a dynamometer for elevator inspection and detection is proposed. Content of the Utility Model

[0017] The handle is movably connected inside the activity groove through an activity pin.

[0018] Preferably, an elastic band is sleeved outside the dynamometer body.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] By inserting the protection frame into the inside of the return groove, then under the elastic force of the spring, the fixing rod will be driven to move. After one end of the fixing rod is clamped inside the clamping hole, the protection frame can be fixed. Since the spring always applies a force to the fixing rod, the stability of the fixing rod can be guaranteed, so that when the dynamometer body vibrates, the fixing rod will not fall off from the clamping hole. Compared with the existing ones, the protection frame in the present utility model has better stability, ensuring the protection effect of the protection frame on the hook;

[0021] When the dynamometer body needs to be used, by pulling the auxiliary plate to pull the fixing rod, at this time the spring will perform a corresponding stretching movement. After one end of the fixing rod disengages from the clamping hole, the protection frame can be disassembled, and at this time the hook will be exposed. Therefore, the present utility model is convenient for disassembling the protection frame, improving the overall working efficiency.

[0022] Since the handle is movably connected inside the activity groove through an activity pin, when the dynamometer body needs to be taken, the dynamometer body can be directly taken by using the handle, which is relatively convenient;

[0023] When the dynamometer body is in use, the handle is fixed by using the elastic band to prevent the handle from affecting the work of the dynamometer body, which helps to improve the working efficiency of the dynamometer body. Description of the Drawings
