The rocker arm includes a rod and a handle connected to one end of the rod. The rod is angled to the side wall of the housing, and the other end of the rod is threadedly connected to the input shaft of the gear transmission mechanism. The structure is simple and compact, reducing the volume occupied during carrying and making it easy to carry.

[0004] In practice, most portable hand-cranked generators have detachable and retractable cranks. However, because portable hand-cranked generators are used for carrying around, the long-term bumpy roads and repeated use can easily cause the detachable crank to fall off during storage or be forgotten to be stored.

[0005] It is evident that the aforementioned problems with existing technologies urgently need to be addressed. Utility Model Content

[0006] In view of the above-mentioned problems in the existing technology, one aspect of the purpose of this utility model is to provide a portable hand-cranked generator to solve the problems that the detachable crank is easily dropped or lost due to being forgotten to be stored away when the hand-cranked generator is continuously carried and used repeatedly.

[0007] To achieve the above objectives, this utility model provides a portable hand-cranked generator, including a generator assembly. An "L"-shaped rocker arm slot is provided on one outer wall of the generator assembly to engage the rocker arm assembly. A slot is provided on the outer wall of the generator assembly, and a push-button switch is provided inside the slot. A number of power sockets are provided inside the rocker arm slot. The rocker arm assembly is driven to be inserted into the slot to keep the push-button switch on, thereby keeping the power sockets on.

[0009] Preferably, the slot has a magnetic plate inside.

[0010] Preferably, the rocker arm slot has a fixing groove inside, and the fixing groove has a magnetic plate inside to accommodate and fix the rocker arm assembly.

[0011] Preferably, the rocker assembly includes a rocker arm, the end of which is provided with a plug.

[0012] Preferably, the insert is made of a single piece of magnetic material.

[0013] Beneficial effects:

[0014] Compared with the prior art, the portable hand-cranked generator provided by this utility model has the following beneficial effects:

[0015] 1. The push-button switch inside the slot ensures that the joystick is inserted into the slot before the power sockets can be powered on. This serves as a reminder to the user to prevent the joystick from being lost.

[0016] 2. The rocker arm slot is located on the outer wall of the generator assembly and is a relatively obvious "L" shaped groove. When the rocker arm is not inserted and stored inside, the groove can be clearly seen on the outer wall of the generator assembly, which can remind the user to avoid losing the rocker arm.

[0017] 3. The magnetic suction plate inside the fixing slot can fix the rocker arm in place, preventing the rocker arm assembly from falling off when the generator assembly moves, and also protecting the power socket. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, a portable hand-cranked generator includes a generator assembly 1. An "L"-shaped rocker arm slot 102 is provided on one outer wall of the generator assembly 1 to engage a rocker arm assembly 2. A slot 106 is provided on the outer wall of the generator assembly 1. A push-button switch 107 is provided inside the slot 106. A number of power sockets 103 are provided inside the rocker arm slot 102. The rocker arm assembly 2 is driven to be inserted into the slot 106 to keep the push-button switch 107 on, thereby keeping the power sockets 103 on.

[0026] The main purpose of this portable hand-cranked generator is to ensure that the crank 201 is inserted into the slot 106 via a push-button switch 107 inside the slot 106, so that the power sockets 103 can be powered on for use. This serves as a reminder to the user to prevent the crank 201 from being lost. Furthermore, the crank slot 102 is a clearly visible "L"-shaped groove on the outer wall of the generator assembly 1. When the crank 201 is not inserted, the groove is clearly visible on the outer wall of the generator assembly 1, reminding the user to avoid losing the crank 201. Additionally, the fixing slot 104 contains a magnetic plate, which securely stores the crank 201 within the crank slot 102, preventing the crank assembly 201 from falling off when the generator assembly 1 is moved, and also protecting the power sockets 103.

[0027] In the technical solution provided by this utility model, by Figure 1 , Figure 2 and Figure 3 It is known that the generator assembly 1 includes a generator body 101, which can perform hand-cranked power generation. The generator body 101 is provided with a rotating block 105 to fit onto the outer wall of the slot 106. The rotating block 105 is connected to the power generation mechanism inside the generator body 101. The rocker arm 201 is inserted into the slot 106 and can drive the rotating block 105 to rotate, thereby performing hand-cranked power generation.

[0028] Furthermore, the slot 106 has a magnetic plate inside, which allows the insert 202 to be magnetically attached and locked into the slot 106, preventing it from falling off naturally.

[0029] Furthermore, the joystick slot 102 also has a fixing groove 104 inside, which can be used to insert the plug 202 and drive the joystick 201 to be locked in the joystick slot 102. The fixing groove 104 is also a magnetic plate inside to store and fix the joystick assembly 2, so as to prevent the joystick 201 from falling off naturally. Since the joystick slot 102 is located on the outer wall of the generator assembly 1, if the joystick 201 is not stored inside, there will be a clear groove on the outer wall of the generator assembly 1, which can remind the user to avoid losing the joystick 201.

[0030] Furthermore, the rocker assembly 2 includes a rocker 201, and the end of the rocker 201 is provided with a plug 202.

[0031] Furthermore, the insert 202 is made of a single piece of magnetic material, which can be attached to the inside of the slot 106 and the fixing slot 104 respectively, preventing the rocker arm 201 from falling off naturally.

[0032] Working principle: When it is necessary to use the generator assembly 1 to generate electricity, the user forcefully pulls the rocker arm 201 out of the rocker arm slot 102, and then magnetically inserts the plug 202 into the slot 106. Thus, by rotating the rocker arm 201, the rotating block 105 can be driven to rotate, thereby performing hand-cranked power generation.

[0033] Furthermore, when the plug 202 is inserted into the slot 106, the push switch 107 inside the slot 106 is pressed and turned on, thereby turning on each power socket 103 and enabling power supply.

[0034] When the generator assembly 1 is finished using, the user pulls out the rocker arm 201. At this time, the push switch 107 is disconnected through the torsion spring hinge, and the power socket 103 is also disconnected.

[0035] Then, insert the plug 202 into the fixing groove 104 for adsorption and fixation, so that the rocker arm 201 fits into the rocker arm slot 102, keeping the outer wall of the generator assembly 1 intact, making it easy to move, and protecting the power socket 103.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
