[0032] The preferred embodiments of the present invention will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that similar reference numerals denote similar elements in the following drawings, and thus, once an element is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0034] This embodiment mainly elaborates on the electric start fixing seat of a backpack lawn mower that facilitates battery pack replacement and does not accidentally touch the motor switch, as follows:

[0035] As Figures 1-6 shown, the electric start fixing seat of the backpack lawn mower includes a fixing seat main body 01. There are two mounting holes that are vertically distributed and cross - arranged on the fixing seat main body 01. The fixing seat main body 01 is connected to a handle and a long rod (the handle and the long rod are not shown in the attached drawings of the specification) through the two mounting holes. A base 2 is detachably installed below the fixing seat main body 01 by screws. A plug 3 is clamped and installed between the fixing seat main body 01 and the base 2. The battery pack 1 is slidably installed on the fixing seat main body 01 and the base 2 and is connected to the plug 3. The battery pack 1 can be restricted from sliding off by structures such as a buckle, realizing the detachable installation of the battery pack 1.

[0036] Since the fixing seat is used to connect the handle and the long rod, in this application, by installing the battery pack 1 on the fixing seat, when the lawn mower is used with it on the shoulder, the battery pack 1 is located in front of the operator. After the battery pack 1 runs out of power, it is convenient to replace the battery pack 1.

[0037] As Figures 3-5 shown, the fixing seat main body 01 includes a main seat 5, a connecting seat 7, and a top seat 8. The connecting seat 7 is arranged between the main seat 5 and the top seat 8 and is fixedly connected by a number of screws. An installation hole is formed between the main seat 5 and the connecting seat 7, and another installation hole is formed between the top seat 8 and the connecting seat 7.

[0038] An electrical cavity a is formed between the fixed main seat 5 and the base 2. An electric start button 4 is installed on the main seat 5, and the plug 3 is provided with a protruding electrical connection part 31. The electrical connection part 31 is inserted into the electrical cavity a. The electric start button 4 is directly connected to the plug 3, or connected by a wire, or integrated on the same circuit board.

[0039] Normally, the electric start button 4 is set on the handle. However, when the lawn mower is in use, the operator's hand holding the handle is likely to touch the electric start button 4, resulting in accidental touch operations. Therefore, the electric start button 4 is installed on the main seat 5, which can also effectively avoid accidental touch operations by the operator and ensure the stable operation of the motor when the lawn mower is in use.

[0040] As Figures 3-6As shown, the electric start button 4 is used to control the start or shutdown of the lawn mower motor. Therefore, there will be a connecting wire between the electric start button 4 and the motor (the motor and the wire are not shown in the attached drawings of the specification). The wire is connected to the electric start button 4 in the electrical cavity a and extends out of the electrical cavity a to be connected to the motor.

[0041] To prevent the battery pack 1 from dropping directly, there are two inner edge portions 21 provided on the base 2. A part of the inner edge portion 21 is attached to the main seat 5, and a channel b is formed between the inner edge portion 21 and the main seat 5. The channel b communicates with the electrical cavity a. Another part of the inner edge portion 21 is spaced from the main seat 5 to form an intermediate groove f. The battery pack 1 is slidably mounted on the inner edge portion 21 and the intermediate groove f.

[0042] There is a socket 51 provided on the main seat 5, and an insertion section 22 is provided at one end of the inner edge portion 21 of the base 2. The side of the socket 51 is open. The base 2 is inserted into the side opening of the socket 51 through the insertion section 22, and the base 2 and the main seat 5 are fixedly mounted by screws. The side opening of the socket 51 communicates with the channel b.

[0043] An arc-shaped piece 6 is clamped and installed between the main seat 5 and the connecting seat 7. Due to the arc-shaped setting of the arc-shaped piece 6, a partition groove c is formed between the arc-shaped piece 6 and the main seat 5. The socket 51 is open at the top. The socket 51 communicates with the partition groove c. And there is an outlet 52 provided on the main seat 5 that communicates with the partition groove c. In this embodiment, the wire connecting the electric start button 4 sequentially passes through the electrical cavity a, the channel b, the socket 51, the partition groove c, and the outlet 52 and is connected to the motor.

[0044] The setting of the arc-shaped piece 6 enables that when the main seat 5 and the connecting seat 7 clamp and fix a handle or a long rod, the outer walls of the handle and the long rod will not contact the wire. That is, when the position of the handle or the long rod is adjusted on the fixed seat body 01, it will not cause wear of the outer wall of the handle or the long rod on the wire.

[0045] In other embodiments, the arc-shaped piece 6 may not be installed, and there are an arc-shaped hole and a groove both open at the top provided on the main seat 5. The bottom of the groove is lower than the hole wall of the arc-shaped hole, and the outlet 52 penetrates through the groove wall of the groove.

[0046] As Figures 2-6 shown, the plug 3 is provided with a power connection portion 32. The power connection portion 32 is exposed between the two inner edge portions 21. And the plug 3 is provided with a connection block 33. Both the electrical connection portion 31 and the power connection portion 32 are provided on the connection block 33. And there are protruding limiting portions 34 provided on both sides of the connection block 33. There are two retaining edges d provided on each of the base 2 and the main seat 5, and there are clamping grooves e recessed on the retaining edges d. The connection block 33 of the plug 3 is located between the two retaining edges d, and the limiting portions 34 are located in the clamping grooves e. In the case where the base 2 and the main seat 5 are fixedly connected, the base 2 and the main seat 5 clamp and fix the plug 3 for installation. Preferably, the retaining edges d and the grooves can be provided on the base 2 or the main seat 5.
