Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

As shown in fig. 1-4: the utility model provides a hand-held type safe type gardens weeder, includes casing one 1, casing two 2, locates drive component 3 in casing one 1, locates the cutting component 4 of the rotary type cutting of casing two 2 bottoms, casing one 1 and casing two 2 swing joint, the upper portion and the lower part of drive component 3 can be respectively with casing one 1 and cutting component 4 threaded connection, and the direction of screw thread is unanimous, cutting component 4 rotatable formula is connected in the bottom of casing two 2.

The bottom of the first shell 1 is provided with an annular clamping block 5, and the top of the second shell 2 is provided with an annular clamping groove 6 matched with the annular clamping block 5. The first shell 1 and the second shell 2 are detachably connected through the annular clamping block 5 and the annular clamping groove 6, so that the cutter is convenient to mount and maintain, and parts are convenient to replace.

The cutting member 4 comprises a rotating seat 41 and a plurality of cutting knives 42, the plurality of cutting knives 42 are distributed around the rotating seat 41 at equal angles, and two sides of each cutting knife 42 are sharp parts. The inner edge of the rotating seat 41 is provided with a first internal thread 43, the bottom of the driving component 3 is provided with a first external thread seat 32, the first internal thread 43 is in threaded connection with the external thread seat, the outer edge of the rotating seat 41 is provided with an annular groove 44 with the bottom recessed inwards, the bottom of the shell 2 is provided with an annular clamping seat 7 extending inwards, and the annular clamping seat 7 can be embedded in the annular groove 44 to realize rotating connection.

This scheme still includes the lid that is used for hiding cutting knife 42, prevents sharp blade fish tail hand (because for better demonstration concrete junction between each part, do not give the drawing including the lid in the drawing, and the lid only need with cutting knife 42 size adaptation can).

As shown in fig. 3 to 4, the annular clamping seat 7 is integrally connected with the annular groove 44, specifically, the annular clamping seat 7 is embedded in the annular groove 44, so that the rotating seat 41 can rotate relative to the second housing 2.

The driving member 3 comprises a motor 31, a first external thread seat 32 and a second external thread seat 33, the output end of the motor 31 is connected with the first external thread seat 32, and the top of the motor 31 is fixedly connected with the second external thread seat 33. The inner edge of the top of the first shell 1 is provided with a second internal thread 8, and the second internal thread 8 is in threaded connection with the second external thread seat 33. The thread length of the first external thread seat 32 is smaller than that of the second external thread seat 33. The top of the second external thread seat 33 is provided with a handheld rotating block 9, a motor 31, a first external thread seat 32 and a second external thread seat 33, and the sum of the lengths of the three is greater than the sum of the lengths of the first shell 1 and the second shell 2.

Through rotating hand-held type turning block 9 for two 33 inside internal thread two 8 threaded connection on internal thread 43 and the casing 1 on internal thread 43 and the rotation seat 41 respectively on external screw thread seat 32 and the external screw thread seat, accessible motor 31 drives external screw thread seat 32 and rotates, thereby drives the cutting knife 42 rotation on the rotation seat 41, realizes ruderal cutting. It should be noted that: 1. when the screw thread is connected with the internal thread on the rotating seat 41, the rotating seat 41 needs to be fastened firstly, so that the phenomenon that the screw thread cannot be connected due to synchronous movement is prevented; 2. the adjustment direction of the external thread seat is consistent with that of the thread on the rotating seat 41, so that the external thread seat is prevented from being separated from the thread seat.

This scheme is considered according to the security, set up rechargeable battery annular and hide with casing 1 in, the top of casing 1 is located to its electric contact one, and locate handheld rotor 9's bottom with motor 31 electric connection's electric contact two (being certain arch), only when handheld rotor 9 changes to being close casing 1, motor 31, electric contact two, could become a closed circuit between electric contact one and the battery, the cutting knife 42 just can appear rotating, avoid traditional direct through the switch, the mode of switching off the power leads to the phenomenon that the hand is cut, thereby the security of using improves greatly.

The outer surface of the first shell 1 is provided with a handle 10 and a grass blocking piece 11, and the grass blocking piece 11 is positioned on the lower side of the handle 10. When using, accessible handle 10 is convenient for hold whole weeder is handheld and is clenched, secondly, because in the groove of cutting, the grass can splash, and a small amount of weeds are still comparatively sharp, has the potential safety hazard of cutting the hand, through keeping off the setting of grass piece 11, can avoid the grass that splashes direct and hand contact.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and the protection scope must be determined by the scope of the claims.
