Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: fig. 1 is the utility model discloses a municipal garden uses mechanical scissors, as shown in fig. 1, including casing 1, be equipped with first pivot 3, second pivot 4 and the third pivot 9 that parallel and tip of each other stretched out casing 1 in the casing 1, coaxial fixed has first gear 5 on the first pivot 3, coaxial fixed has second gear 6 on the second pivot 4, coaxial fixed has third gear 10 on the third pivot 9. An opening is formed in one end of the shell 1, the first gear 5 and the second gear 6 are located at the opening, the first gear 5 is meshed with the second gear 6, and the third gear 10 is meshed with the first gear 5. A handle 13 is fixed at one end of the shell 1 far away from the opening, so that the shell is convenient to hold by a single hand.

As shown in fig. 1, when the branches and leaves are trimmed, the branches and leaves fall into the housing 1 from the opening and enter the meshing position of the first gear 5 and the second gear 6, so that the housing 1 is provided with a cleaning hole 1a exposing the meshing position of the first gear 5 and the second gear 6 and the meshing position of the first gear 5 and the third gear 10, and the foreign matters such as the branches and leaves at the meshing position of the gears can be clamped by extending a tool into the cleaning hole 1 a.

As shown in fig. 1, the first gear 5 and the second gear 6 have the same diameter, and the third gear 10 has a larger diameter than the first gear 5, which are located in the same plane. The first gear 5, the second gear 6 and the third gear 10 are all provided with through holes 12 for reducing weight. The end part of the first rotating shaft 3 or the third rotating shaft 9 extending out of the shell 1 is sleeved with a knob 11, the bottom of the knob 11 is provided with a slot, and the tops of the first rotating shaft 3 and the third rotating shaft 9 are matched with the slot in shape.

As shown in fig. 1, a transmission rod 7 is fixed on each of the first gear 5 and the second gear 6, and the two transmission rods 7 are arranged in an X-shape in a crossed manner. The two fixing points of the two transmission rods 7 with the first gear 5 and the second gear 6 are symmetrical about the symmetry axis of the first gear 5 and the second gear 6. The two transmission rods 7 do not interfere with each other when rotating along with the first gear 5 and the second gear 6, the opposite surfaces of the two transmission rods 7 are always attached, and the contact part of the two transmission rods 7 is always positioned on the symmetrical axis of the first gear 5 and the second gear 6.

As shown in fig. 1, the two transmission rods 7 are hinged to the cutter body 2 at ends thereof away from the housing 1 through bolts 8, and the two bolts 8 are symmetrical about the symmetry axes of the first gear 5 and the second gear 6. Two cutter bodies 2 also are the setting of X shape to the crossing department of two cutter bodies 2 also wears to be equipped with bolt 8 as the articulated shaft, and this articulated shaft also is located the symmetry axis of first gear 5 and second gear 6. The cutter body 2 consists of a cutter head 21 and a cutter handle 22 which are positioned on the same straight line, wherein the cutter head 21 is provided with cutting edges, and the cutting edges on the two cutter heads 21 are arranged oppositely.

The implementation principle of the embodiment is as follows: a knob 11 is mounted on the third rotating shaft 9, and the first gear 5 is driven to rotate by rotating the knob 11, so that the second gear 6 rotates towards or away from the first gear 5. When the second gear 6 and the first gear 5 move oppositely, the distance between the ends, far away from the shell 1, of the two transmission rods 7 is increased, the distance between the ends, far away from the transmission rods 7, of the cutter body 2 is also increased, and the mechanical shears for gardens are in an open state; when second gear 6 and first gear 5 back of the body motion, the one end distance that casing 1 was kept away from to two transfer lines 7 diminishes, and the one end distance that transfer line 7 was kept away from to cutter body 2 also diminishes, and the machinery is cut with the gardens and is the merge state, begins to cut branches and leaves this moment.

Example 2: as shown in fig. 2, in embodiment 1, long holes 22a are formed in the two tool shanks 22 in the longitudinal direction, the bolts 8 for hinging the tool body 2 and the transmission rod 7 are positioned in the long holes 22a, and the diameter of the bolts 8 is matched with the width of the long holes 22 a.

When the transmission rod 7 drives the cutter body 2 to open and close, the bolt 8 at the hinged position of the transmission rod 7 and the cutter body slides in the long hole 22a along the length direction of the long hole 22a, so that the distance between the cutter head 21 and the shell 1 is ensured not to be changed greatly.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
