DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, a hand-controlled button-type telescopic suction electrocoagulation hook includes a control handle 1 in the shape of a rectangular strip, an extension rod 2 is connected to the end of the control handle 1, and a sliding channel is reserved in the extension rod 2 for sliding installation of an electric hook 3. An air suction component 4 is installed between the control handle 1 and the extension rod 2 to remove smoke in time, and an electrocoagulation switch 5, an electric cutting switch 6, and a telescopic component 7 linked to the electric hook 3 are installed between the control handle 1 and the electric hook 3. The electrocoagulation switch 5 and the electric cutting switch 6 realize the switching of the working mode of the electric hook 3. An isolation assembly component 8 is installed between the extension rod 2 and the control handle 1. When the electric hook 3 is extended relative to the extension rod 2 for work, the isolation assembly component 8 ensures that the air suction component 4 is ventilated and exhausts smoke normally.

[0024] Specifically, the end of the control handle 1 is pointed, the isolation assembly component 8 includes an assembly hole 81 provided at the end of the control handle 1, and the extension rod 2 is threadedly connected to the assembly hole 81, and the transfer assembly can be completed manually. A telescopic channel 82 for the power supply hook 3 to slide and retract is opened in the center of the extension rod 2, and an air suction channel 83 is arranged in a centrally symmetrical manner relative to the telescopic channel 82. The telescopic channel 82 is relatively independent from the air suction channel 83, and provides support for the sliding of the power hook 3.

[0025] In depth, the air intake component 4 includes an air intake switch 41 arranged on the outside of the control handle 1 and an air intake chamber 42 arranged inside the control handle 1. A one-way valve 43 is installed in the air intake chamber 42 to realize one-way air intake. A wiring channel 44 is arranged inside the control handle 1, which is adjacent to the air intake chamber 42 and opposite to the air intake switch 41. The air intake switch 41 is connected to the main control module via a control line arranged in the wiring channel 44.

[0026] Furthermore, the telescopic component 7 ensures the sliding storage of the electric hook 3, and specifically includes a telescopic switch 71 slidably installed on the outside of the control handle 1, the telescopic switch 71 is fixedly connected to the electric hook 3, and a linkage component is installed between the telescopic switch 71 and the suction chamber 42 to control the internal flux of the suction chamber 42.

[0027] Furthermore, the linkage assembly includes a linkage cylinder 72 connected to the telescopic switch 71, the linkage cylinder 72 is slidably inserted in the air inlet 42, and the linkage cylinder 72 is axially arranged with a large air inlet 73 and a small air inlet 74, and the large air inlet 73 and the small air inlet 74 are respectively arranged symmetrically with respect to the linkage cylinder 72. When the telescopic switch 71 slides, the linkage cylinder 72 also slides axially relative to the control handle 1, and the internal flux of the air inlet 42 is adjusted as the large air inlet 73 and the small air inlet 74 are switched, and the small flux state is maintained when the electric hook 3 is in the storage state.

[0028] In addition, in order to facilitate operation and holding, the suction switch 41 and the telescopic switch 71 are arranged on both sides of the control handle 1 and are in the same radial position relative to the control handle 1. The electrocoagulation switch 5 and the electrocuting switch 6 are used more frequently than the suction switch 41 and the telescopic switch 71.

[0029] At the same time, the electrocoagulation switch 5 and the electrocuting switch 6 are installed on the outside of the control handle 1 and arranged axially adjacent to the control handle 1. The electrocoagulation switch 5 and the electrocuting switch 6 are located between the suction switch 41 and the telescopic switch 71 for easy triggering and pressing.

[0030] It can be seen that in order to ensure that the electric hook 3 can be normally received in the extension rod 2, the length of the bent portion of the end of the electric hook 3 is smaller than the inner diameter of the extension rod 2, and the electric hook 3 is isolated from the extension rod 2, with a gap for air flow. The extension rod 2 is usually made of insulating material to protect the electric hook 3.

[0031] Obviously, the outer side of the control handle 1 is covered with an anti-skid layer to ensure the stability of holding. Usually, the anti-skid layer is made of frosted material to ensure the contact friction with the hand.

[0032] Preferably, the control handle 1 is provided with a transfer port 11 away from the extension rod 2, and a circumferential sealing groove 12 and a sealing protrusion 13 are arranged in the transfer port 11. The transfer port 11 is plugged and fixed with a corresponding hose, and contains an independent ventilation duct and control and power supply cables.

[0033] To sum up, the principle of this embodiment is that the electric hook 3 is telescopically extended relative to the extension rod 2 under the action of the telescopic component 7, wherein the isolation assembly component 8 provides a sliding channel for the electric hook 3, and the isolation assembly component 8 also reserves a ventilation channel for the suction component 4 to ensure that the sliding storage of the electric hook 3 does not affect its normal smoke exhaust.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although this article uses more terms such as control handle 1, adapter 11, sealing groove 12, sealing protrusion 13, extension rod 2, electric hook 3, suction assembly 4, suction switch 41, suction cavity 42, one-way valve 43, wiring channel 44, electrocoagulation switch 5, electric cutting switch 6, telescopic assembly 7, telescopic switch 71, linkage cylinder 72, large air inlet 73, small air inlet 74, isolation assembly assembly 8, assembly hole 81, telescopic channel 82, suction channel 83, etc., it does not exclude the possibility of using other terms.
