Embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

Like Fig. 1 ~ shown in Figure 8,1. beat the grass assembly, 15. joint pins, 16. link slots, 161. limited shoulders, 2. handle, 21. upper handles, 22. lower handles, 23. switches, 24. hook grooves, 25. connectors, 251. limited blocks, 26. external power supply wires, 3. horizontal barb, 31. anti-skidding striped buttons, 4. spring, 5. public plug-in unit, 6. connecting ring, 7. lower cover, 8. mother board, 9. loam cake, 10. inner conductors of head on the head, 11., 12. times heads, 13. motors, 14..

The dual-purpose type mower, as shown in Figure 1, belong to a kind of afforestation electric tool; Mainly be to constitute, motor 13 be housed in the head and, switch 23 and external power supply wire 26 be housed on the handle 2 by the motor-driven assembly 14 of beating the grass by the head 1 of front end and 2 on the handle of rear end; Be connected through inner conductors 10 between switch 23 and the motor 13 simultaneously; After the external power supply wire energized, get final product starter motor 13, and drive assembly 14 work of beating the grass through console switch 23.

Described head 1 is to be linked into an integrated entity with screw after head 11 fastens mutually with following head 12 by plastic going up, and head 1 rear end extends back columniform joint pin 15, is designed with mounting groove and link slot 16 on this joint pin.

The horizontal barb 3 of spring 4 pushing tows is installed in the described mounting groove; This spring is vertical installment state; Its two ends respectively pushing tow in mounting groove with horizontal barb on, so horizontal barb under normal conditions by the outside pushing tow of spring and be exposed at joint pin 15 surfaces outward, can prevent that so also inefficacies from appearring connecting in horizontal barb 3; Simultaneously horizontal barb outer surface also is provided with anti-skidding striped button 31, skids when preventing to operate.Described horizontal barb 3 has two, and these two horizontal barbs are that the center is symmetrical distribution with the axle center of joint pin 15.

Described link slot 16 inserts mouthful backwards, just like Fig. 4, Fig. 6, the rearward end that is positioned at joint pin 15 shown in Figure 7, on the cell wall of the both sides of link slot 16, also is provided with limited shoulder 161, and link slot also can be designed with and horizontal barb 3 corresponding two.

Described handle 2 is to fasten the back mutually by plastic upper handle 21 and lower handle 22 to link into an integrated entity with screw; This handle front end is provided with connecting hole; Also be provided with connecting ring 6 simultaneously; The joint pin 15 of above-mentioned head 1 could be connected in this connecting hole by plug-in mounting after need passing connecting ring 6, so connecting ring mainly plays fixing upper and lower handle and the effect of holding joint pin 15 tightly.

Also be respectively equipped with two the hook grooves 24 that are symmetrically distributed on the handle 2 as shown in Figure 2 and two connectors 25 that are symmetrically distributed on the described connecting hole inwall.Described hook groove 24 can be equipped with mutually with each the horizontal barb 3 on the joint pin 15 and form and connect locking; Horizontal barb 3 as shown in Figure 5 is connected locking with hook groove 24 after; This mower promptly is in the state of beating the grass; And making horizontal barb 3 break away from hook groove 24 through pushing anti-skidding striped button 31, extraction can separate head 1 and handle 2; Make another horizontal barb be connected locking with hook groove 24 like Fig. 7, nose-high shown in Figure 8 after rotating 180 °, this mower promptly is in the deburring state.The quantity of hook groove 24 also is two that are symmetrically distributed, and so just can strengthen connecting the effect of locking.

Described connector 25 can coincide equippedly with link slot on the joint pin 15 16, also has additional the limited block 251 equipped with the limited shoulder of link slot 161 simultaneously in the connector both sides.When joint pin 15 is inserted in the connecting hole and through after

horizontal barb

3 and 24 lockings of hook groove; Connector 25 in the connecting hole also gets into from the insertion mouth of link slot 16; And form equipped through limited block 251 and limited shoulder 161; The structure of setting up above-mentioned link slot 16 and connector 25 mainly plays tensioning and the effect that firmly is connected, and prevents the phenomenon of rocking, getting loose after being connected appears when the state of beating the grass of mower is changed with the deburring state in head 1 and handle 2.

Described motor 13 is designed to detachable socket connection structure with the inner conductors 10 that switch 23 is electrically connected, and can make things convenient for separating fully of head 1 and handle 2 through this structure, and instant packed transportation can realize quick conduction at head again during with the handle grafting simultaneously.

This detachable socket connection structure such as Fig. 1, shown in Figure 3 mainly are the public plug-in units 5 that is provided with fixed connection in head 1 rear end, and are provided with the inner conductors 10 that is electrically connected between the motor 13 in this public affairs plug-in unit and head 1; And the corresponding mother board 8 that is provided with fixed connection of handle 2 front ends; Also be provided with the inner conductors 10 that is electrically connected between the switch 23 in this mother board and the handle 2; And mother board also is provided with the loam cake that is fastened and connected mutually 9 and lower cover 7 outward to protect, so just formed detachable socket connection structure between the male and female plug-in unit.

Can realize the beating the grass quick conversion of function and trimming function of this mower, beat the grass state such as Fig. 4 ~ shown in Figure 6, the deburring state is as shown in Figure 8.

Function can be as shown in Figure 6 when trimming function is changed when beating the grass; Need push the locking that pushing tow elastic force that anti-skidding striped button 31 overcomes spring 4 breaks away to hook groove 24 horizontal barb 3 earlier, this moment is according to extracting head 1 and handle 2 respectively shown in the direction of arrow in opposite directions, in the moment of head with the handle disengaging; The male and female plug-in unit also breaks off connection; With the protection personal security, as shown in Figure 7 then head 1 is upwards rotated 180 ° after, the relative handle 2 of head is the deburring state; So only need as shown in Figure 8 head 1 and handle 2 plug-in mounting one again get final product, but also socket connection and be "on" position of male and female plug-in unit at this moment.

Head 1 is simple and convenient with the fast joint structure dismounting of handle 2 in the utility model; Firm and reliable connection, be difficult for getting loose; And do not need just can accomplish the dual-use type that little, in light weight, the instant packed transportation of machine volume has also reduced production cost simultaneously by other instruments.
